Promptly
Promptly is a B2B SaaS CMS for LLM prompts - founded and built by Dan Barclay. It exists on a simple thesis: your prompts don't belong in your codebase. They belong with the domain experts who actually know how to write them.
Problem
AI features ship with prompts hard-coded in application repositories. Every tweak to wording, tone or behaviour is gated on an engineer, a code review and a deploy. Meanwhile the people who actually know the domain - support leads, marketers, legal, product - can't touch the prompt that defines how the AI represents the company.
Solution
A CMS purpose-built for prompts. Versioned, environment-scoped, type-safe at runtime via the Promptly SDK. Domain experts write and release prompts in the dashboard. Engineers consume them with a single typed function call. Used in production by 100+ companies.
